SKC offer two battery charger options for the Universal MAZ series pumps, a single charger (Part No. 223-203A) and a five station charger (Part No. 223-

103A). Both charger models provide optimum charging of the NiMH battery packs used in the Universal MAZ series pumps, based on a timed (16 hour) constant current charging phase followed by a switch to a trickle charging rate to prevent overcharging.

The pump controls are situated beneath a clear anti-tamper cover, requiring a tool for removal. This helps prevent tampering during a sample run.

Automatic pump shutdown in the event of a low battery condition. Prevents degradation of battery pack due to over-discharge.

Built in rotameter to indicate airflow during sampling. Gives visual indication of changes in flow rate during a sample due to filter loading or constricted tubing for example. Note the flow indicator must not be used to calibrate the sample flow rate.

Built in replaceable filter to trap particles that would otherwise contaminate the pump mechanism.

2) Care of Universal MAZ Series Pumps

• Always use the correct SKC batteries and battery chargers designated for the Universal MAZ series pumps.

• Never run the pump long term without a tube or filter medium in place.

• When carrying out sampling using long term colour change tubes always use a tandem tube holder with trap tube (Part No. 222-3D-2 and cover 224-29T). This will prevent the aggressive fumes generated by these tubes from entering and damaging the pump mechanism.

• When carrying out sampling using impingers always fit a trap between the impinger and pump inlet.

This will prevent the possibility of the fluid used in the impinger from entering and damaging the pump mechanism. As a further precaution always ensure that the pump flow rate is set to below 1 litre/min before connecting the trap and impinger to the pump inlet. For stability use the accessory mounting screws (refer to pump diagram on pages 8 and 9) to fix the impinger bracket to the front of the pump.

• The Universal MAZ series pump cases are IP55 rated, and therefore must not be used where they may be subjected to high pressure water jets or complete immersion in water. The pumps can be used where they may be subjected to rain, splashing water or low pressure water jets, but care must be taken to ensure that water cannot enter the pump air inlet port.

Page 6 224-UMAZM Issue A www.skcltd.com

General Information

• Universal MAZ series pumps are fitted with a particulate filter which is easy to replace. For general maintenance replace the filter every 2-3 months or if it appears dirty. New filters are white in colour (order

Part No. P2240901).

Warning - Failure to follow these guidelines will void the product warranty.

3) Non ANZEx Certified Variants of the Universal Pump

The Universal pumps are also produced in a variant ranges which are UL or ATEX certified for intrinsic safety and these pumps are therefore not suitable for use in potentially explosive atmospheres in Australia and New

Zealand where ANZEx or IECEx approval is required.

Pump components vary between the ANZEx, UL and ATEX certified variants, therefore components must not be interchanged between these pumps. If in any doubt please contact SKC Ltd customer services for advice.

4) Sampling Methods

This instruction manual provides the necessary information to set up and operate the Universal MTX series pumps. For more detailed information on specific sampling methods please refer to SKC’s Step-By-Step

Guide to Air Sampling (Part No. 224-G1). To obtain a free copy please contact SKC Ltd customer services on

Getting Started

APPLICABLE TO ALL MODELS

1) Charging the Battery Pack

Prior to first use the battery pack should be fully charged, ideally overnight.

The Universal MAZ series pumps must only be charged using the correct SKC chargers (Part Nos. 223-203A

- single charger, 223-103A - five station charger).

The charger is supplied with mains input plugs suitable for use in the UK, Europe, USA and Australia / New

Zealand. Select the correct mains input plug and fit it to the charger.

Plug the charger output jack plug into the mating socket at the rear of the battery pack. Plug the charger into the electrical mains supply and switch on the power. The LED indicator on the charger will illuminate to indicate that the charger is charging at full rate.

After 16 hours the charger will automatically switch to trickle charge, identified by the LED indicator on the charger flashing on and off.

When fully charged disconnect the charger jack plug from the battery pack.

2) Accessing the Controls

To access the controls unfasten the screw retaining the anti-tamper control cover (No. 9) using the large bladed screwdriver attachment of the supplied toolkit, and remove the cover to access the controls.

Note: The anti-tamper control cover forms part of the IP55 rated pump casing and therefore must not be removed whilst in a hazardous location. Set up the pump and start the sample, as detailed in the following sections, whilst in a safe location and ensure that the anti-tamper control cover is securely fitted before taking the pump into the hazardous location.

www.skcltd.com 224-UMAZM Issue A Page 11

www.skcltd.com 224-UMAZM Issue A Page 13

Operating the Timer (224-PCMAZ8 Only)

The timer function features three settings used to achieve the various modes of operation:

1. DELAYED START - The time period in minutes that will elapse prior to the pump starting to run. Setting this value to zero disables the delayed start function.

2. SAMPLE PERIOD - The time period over which sampling will occur. Works in conjunction with the PUMP

PERIOD. Setting this value to zero will disable the timed run function and the pump will run continuously until stopped using the START/HOLD key.

3. PUMP PERIOD - The time period in minutes during which the pump is actually running. If the PUMP

PERIOD is set the same or to a higher value than the SAMPLE PERIOD, the pump will run continuously for the duration of the SAMPLE PERIOD. If the PUMP PERIOD is set to a lower value than the SAMPLE

PERIOD then the pump will automatically calculate on and off periods to apportion the required PUMP

PERIOD time over whole of the SAMPLE PERIOD time.

Setting a Simple Timed Run

Example: 8 hour timed run with no delayed start.

1. Switch the pump on and press the START/HOLD key to enter hold mode.

2. Press the SET-UP key to enter setup mode.

3. Press the MODE key to cycle to the SAMPLE PERIOD setting option. The right hand digit will be flashing.

4. The timer is set in minute values. Calculate the required sample period in minutes - 8 hours = 480 minutes.

Thefore the right hand digit should be set to 0.

5. Press the DIGIT SELECT key to select the second digit from the right.

6. Press the DIGIT SET key to increment the digit to 8.

12. Press the DIGIT SET key to increment the digit to 8.

13. Press the DIGIT SELECT key to select the third digit from the right.

14. Press the DIGIT SET key to increment the digit to 4. The digits should now read 0480.

15. Note that if a SAMPLE PERIOD time is entered, but the PUMP PERIOD is left at 0000, the pump will run continuously for the duration of the SAMPLE PERIOD.

16. The pump is now set to start after a delay of 2 hours, run for 8 hours and then switch off. To start the timed run press the START/HOLD key. The LCD screen will show the legend DELAYED START flashing in the bottom left of the screen and the start delay time will count down from 120 minutes. At the end of the start delay the pump will automatically start and the legend SAMPLE PERIOD will flash on and off in the top right of the LCD screen. At the end of the 8 hours (480 minutes) the pump will automatically stop and the display will show the legends HOLD and SAMPLE OVER, and the elapsed run time. Should the pump prematurely stop during the sample period the actual elapsed run time will be displayed.

Setting an Intermittent Sample

Intermittent sampling allows a sample to be taken over a period of up to 9999 minutes (approximately one week) and can prove extremely useful for environmental or ambient monitoring. To sample over a period of one week and produce an average measurement, the pump is set to actually draw air for a period that the battery can handle such as 8 hours over the 7 day period.

Page 16 224-UMAZM Issue A www.skcltd.com

Operating the Timer (224-PCMAZ8 Only)

Example: 8 hours running over a period of 24 hours

1. Switch on the pump and enter SET-UP mode. A DELAYED START time can be entered if required.

2. Press the MODE key to cycle to the SAMPLE PERIOD setting and enter 1440 minutes (24 hours) using the

DIGIT SELECT and DIGIT SET keys.

HOLD key. The pump will now repeat the timed run from the start.

To quickly clear a timed run from the pump’s memory switch the pump off and on using the ON/OFF switch.

Note: The battery pack can be safely charged when the pump is left switched on.

www.skcltd.com 224-UMAZM Issue A Page 17

Low Flow Sampling

The standard compensated flow range of the Universal MAZ series pumps is 1000 to 2500 ml/min. To operate at flows in the range 5 to 500 ml/min an optional low flow adapter / tube holder is required. Low flow adapters are available for simultaneous sampling using one, two, three or four sample tubes (refer to the sampling accessories guide on pages 26 and

27 for details). The low flow adapters incorporate throttle valve(s) to set the low flow rate.

To work with the low flow adapter the pump incorporates a ‘constant pressure controller’ regulator to provide a constant suction at the outlet of the low flow adaptor, ensuring stable airflow through the sample tube(s) once the flow has been set using the throttle valve(s).

To enable or disable low flow mode a low flow mode control is located beneath the smaller of the two knurled metal cap screws on the top of the pump.

Unscrew and remove the cap screw, and use the large bladed screwdriver attachment of the supplied toolkit to unscrew the low flow mode control anti-clockwise by three turns to enable low flow mode.

To disable low flow mode screw the low flow mode control in fully clockwise.

To Set Up For Low Flow Sampling -

First ensure that low flow mode is disabled as detailed above. Ensure that the low flow adapter is not connected to the pump inlet hosetail at this point.

Page 18 224-UMAZM Issue A www.skcltd.com

Stand the pump upright on a level surface and set the pump running. Set the pump flow rate to approximately

1500 ml/min. The built in flow indicator rotameter can be used to make this setting as only an approximate flow rate is required.

Turn off the pump and enable low flow mode as previously detailed.

No further adjustment of the pump flow rate is required.

The low flow adapter can now be connected to the pump inlet hosetail. Set the low flow rate with the throttle valve on the low flow adjuster, using a suitable flow calibrator (such as a Defender primary calibrator).

Note: Always check that low flow mode has been disabled before carrying out high flow sampling subsequent to low flow sampling using the same pump.

• Filter media back pressure too high. Try a lower flow rate and/or a less restrictive filter media if the sampling method being used allows this.

• Pump is in the low flow mode. Disable low flow mode.

• Pump valves leaking. Replace valve plate assemblies.

Page 20 224-UMAZM Issue A www.skcltd.com

Troubleshooting

Possible Fault

Pump stops due to low battery before the end of the required sample period

Corrective Action

• Battery pack not fully charged before starting sample run. Ensure battery pack is fully charged before starting a sample run.

• Battery pack has reduced capacity as it nears end of life. Replace the battery pack.

• Filter media back pressure too high. Try a lower flow rate and/or a less restrictive filter media if the sampling method being used allows this.

www.skcltd.com 224-UMAZM Issue A Page 21

Care of the Battery Pack

Battery Charging

• Charge battery pack fully before first use to ensure optimum performance.

• Full battery capacity will be acheived after 2 to 3 full charge / discharge cycles.

• Use only SKC approved charger designated for this battery pack. Use of a non-SKC approved charger may impair battery performance or even cause irrepairable damage, and will invalidate the battery pack warranty.

Battery Performance

• Charging temperature - For optimum performance charge NiMH batteries between 0 and +40°C.

• Do not overcharge - For optimum performance disconnect battery pack from charger after 24 hours.

• Discharge temperature - For optimum performance discharge NiMH batteries between -10 and +45°C

(refer also to pump specifications on page 3 for other limitations on operating temperature for intrinsically safe applications).

Battery Maintenance

• Battery cycling during regular use - To maintain optimum capacity during regular battery use, cycle battery once a month. Run pump until low battery shutdown occurs, then fully charge battery.

• Long term storage and highly infrequent use -

1. Charge battery fully prior to long term storage.

2. Store in a cool, dry place at temperature between 0 and 30°C.

3. Recharge battery at least once a year (or more frequently if stored at temperature above 30°C).

4. Cycle battery 2 to 3 times after long term storage to restore optimum capacity.

Page 22 224-UMAZM Issue A www.skcltd.com

Care of the Battery Pack

Battery Testing

1. Connect SKC approved charger to battery pack. If charger indicator LED illuminates, battery pack charger input is ok. If charger LED does not illuminate, battery pack input fuse is blown - Replace battery pack.

2. Leave battery pack connected to charger to fully charge.

3. If pump does not function at all after full charge of battery pack, battery pack output fuse has blown, or battery cells have failed or are at end of life - Replace battery pack.

4. If pump functions after full charge of battery pack but gives significantly reduced run times before low battery shutdown, battery cells are failing or are at end of life - Replace battery pack.

Battery Replacement

Refer to pump diagram on page 8. To remove the battery pack unscrew and remove the two battery screws

(No. 25). Carefully slide the battery pack sideways out from under the metal belt clip (No.22) and remove the battery pack.

Fit the replacement battery by sliding it under the metal belt clip. Take care to ensure that the pins of the pump power connector engage into the holes in the socket connector on the battery pack. Secure the battery pack with the two screws.

Battery Disposal

• SKC Ltd recommends that all batteries and battery packs are disposed of correctly at the end of their working life. This means that they should be collected and treated separately from other waste.

• Please ensure that any end-of-life SKC battery packs are collected and recycled or disposed of correctly.
